These drawings and written description are not intended to limit the scope of the disclosed concepts in any way, but rather to illustrate the concepts of the disclosure to those skilled in the art by reference to specific embodiments.
Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
The following are embodiments of the disclosed apparatus that may be used to perform embodiments of the disclosed methods. For details not disclosed in the embodiments of the apparatus of the present disclosure, refer to the embodiments of the method of the present disclosure.
Fig. 1 is a system architecture diagram of a wlan access method of the present disclosure, as shown in fig. 1, the method is applied to a wlan, for example, a wlan in a home, where the method relates to a wireless access node (AP), a relay, and a terminal, where the AP may be a wireless router, and the relay may be a device that has successfully accessed to the wlan, that is, the relay is any terminal that establishes a connection relationship with the AP. The terminal is a device to be accessed to the wireless local area network. After the terminal successfully accesses the wireless lan, the terminal may also assume the role of a relay in addition to completing its own function, and further, as shown in fig. 1, when a new terminal desires to access the wireless lan, the new terminal may access the wireless lan through the access AP or through the access relay, so as to achieve flexibility of access and ensure quality of transmission signals.
The station is described in terms of a terminal, and mainly relates to a process of determining that an access device is selected as an AP or a specific relay when the terminal accesses a wireless local area network.
Fig. 2 is a flowchart illustrating a wlan access method according to an exemplary embodiment, where as shown in fig. 2, the method is performed as follows:
in step S101, the terminal transmits a wireless local area network access broadcast message.
Taking an example of a mobile phone accessing a wireless local area network, when a mobile phone located in a home needs to access the wireless local area network of the home, an access node scan is performed first, that is, a wireless local area network access broadcast message is sent to surrounding nodes, and a Service SetIdentifier (SSID) of an AP of the wireless local area network of the home is carried in the broadcast message.
The mobile phone may obtain the SSID of the AP of the wireless lan of the home in advance by a configuration method or the like, which will be described in detail below.
In step S102, the terminal receives a response message sent by at least one receiving node, where the response message includes an SSID of the at least one receiving node.
After the terminal sends out the wireless local area network access broadcast message, the node receiving the message judges according to the condition of the node, if a receiving node determines that the receiving node has the function of the access node, the receiving node sends a response message to the terminal, and the response message contains the SSID of the receiving node.
In step S103, the terminal determines an access node list according to the SSID of at least one receiving node, where the access node list includes an AP and at least one relay, and the SSID of the at least one relay is calculated by using a preset algorithm according to the SSID of the AP.
After the terminal sends out the access broadcast message of the wireless local area network, as long as the AP in the wireless local area network is in a normal working state, the AP sends out a response message to the terminal, and meanwhile, the node which is used as a relay in the wireless local area network also sends out the response message to the terminal. In addition, some nodes in non-current wireless local area networks may also receive the broadcast message and send a response message to the terminal.
When the terminal receives the response messages, the optional access nodes are screened out according to the SSID, and an access node list is formed. The method comprises the steps that in a specific wireless local area network, an AP has a unique SSID, and further, after a certain node accesses the wireless local area network and serves as a relay, the node serving as the relay also has the unique SSID, and the SSID is generated on the basis of the SSID of the AP according to a preset algorithm. Because the terminal has previously acquired the SSID of the AP of the current wireless local area network, the terminal can identify the AP and the relay in the current wireless local area network according to the SSID and a preset algorithm, and filter out nodes that do not meet requirements, such as nodes in other wireless local area networks.
Through the screening, the access nodes in the access node list determined by the terminal are all nodes which are located in the current wireless local area network and can be accessed by the terminal.
In step S104, the terminal determines a target access node according to a Received Signal Strength Indication (RSSI) of the AP corresponding to the access node list and the RSSI of the relay.
After the terminal screens out the nodes which are positioned in the current wireless local area network and can be accessed by the terminal, a node which can ensure the optimal signal transmission quality can be selected according to the RSSI of the nodes, and the connection with the node is established.
In this embodiment, when a terminal needs to access a wireless local area network, a node that can be an access node in the wireless local area network is determined according to an SSID, where the node includes not only an AP but also a relay, and then a node with the best signal transmission quality is selected from the nodes. Namely, more optional access nodes are provided for the terminal through the SSID, so that the terminal is ensured to select the node with the best signal transmission quality, and the effect of accessing the terminal to the wireless local area network is improved.
On the basis of the foregoing embodiment, the present embodiment relates to a specific method for a terminal to determine a target access node, that is, a specific implementation manner of the step S104 is as follows:
and acquiring the maximum value of the RSSI of the AP and the RSSI of the relay in the access node list, and taking the AP or the relay with the maximum RSSI as the target access node.
The RSSI is an index used for measuring the strength of a received signal, and after the terminal determines the access node list, the RSSI of each node in the access node list is obtained one by one, and the greater the RSSI is, the better the transmission effect is when the terminal transmits a signal with the access node.
For example, assuming that the current terminal is a mobile phone, the mobile phone is currently located in a certain bedroom corner of a home, and the AP of the wireless lan of the home is located in another bedroom corner with a longer distance, at this time, if the mobile phone directly accesses to the AP, the signal quality will be weaker, and if the method disclosed by the present disclosure is used, a plurality of devices have previously accessed to the wireless lan of the home and have a relay function, the mobile phone will select a node with the largest RSSI from the AP and the relays, for example, a smart lamp located in a middle living room of the home, and after the mobile phone accesses to the smart lamp, the quality of signal transmission will be greatly improved compared with that of signal transmission directly accessing to the AP.
In this embodiment, by selecting the node with the largest RSSI as the access node, the quality of signal transmission after the terminal accesses the access node can be greatly improved.
On the basis of the foregoing embodiments, the present embodiment relates to a specific method in which a terminal determines an access node list according to an SSID of at least one receiving node, that is, fig. 3 is a flowchart illustrating a wireless local area network access method according to an exemplary embodiment, and as shown in fig. 3, the foregoing step S103 specifically includes:
in step S201, the terminal adds the AP in the at least one receiving node to the access node list.
Referring to the foregoing description of fig. 1, an AP may be regarded as a router in a wireless local area network, that is, the wireless local area network performs data interaction with the internet through the AP, and therefore, in this step, the AP is first added to an access node list as one of the alternative access nodes of the terminal.
In step S202, if the first receiving node is a relay, it is determined whether the SSID of the first receiving node is obtained according to the SSID of the AP by using a predetermined algorithm, and if so, the first receiving node is added to the access node list.
Wherein the first receiving node is any one of the at least one receiving node except the AP.
The node currently serving as the relay needs to be accessed into the wireless local area network in advance and assumes the role of the relay, and as the relay, the node needs to have its own SSID like an AP.
When the terminal is screening the access nodes, whether the SSID of a certain node meets the requirement of the relay SSID in the current wireless local area network is judged according to the SSID of the AP based on the same preset algorithm, namely whether the SSID of the node is obtained according to a specific preset algorithm on the basis of the SSID of the AP is judged.
In this embodiment, the terminal determines whether the node is an optional access node through the same preset algorithm as that of the relay when generating the SSID, so as to ensure that the selected nodes are all relays in the current wireless local area network and ensure the correctness of the selected nodes.
In another embodiment, a preferred implementation manner of the step S202 is as follows:
and judging whether the SSID of the first receiving node is the combination of the SSID of the AP and a preset suffix name or not, and if so, adding the first receiving node into the access node list.
That is, after a certain node is connected to the wireless lan and acts as a relay, the node first acquires the SSID of the AP and adds a preset suffix name to the SSID of the AP. For example, assuming that the SSID of the AP is "TEST" and the preset algorithm is "add suffix-IOT after the SSID of the AP", after a certain node a is used as a relay, the node a generates its SSID as "TEST-IOT" according to the preset algorithm. Since the SSID is a unique identifier of the node, node a needs to send the generated SSID to the surrounding nodes in a broadcast manner, and after another node B also serves as a relay session, although the preset algorithm is the same, the SSID of node B needs to be different from the SSID of node a, so node B may add a corresponding number on the basis of "TEST-IOT" as its own SSID, for example, the SSID generated by node B is "TEST-IOT 1", and node B may also broadcast the generated SSID. By analogy, the SSIDs of other nodes as relays can generate respective SSIDs on the basis of the node B according to the principle of numerical increment.
After the terminal receives the response message of each node, it only needs to judge whether the node is an optional access node according to a preset algorithm "add suffix-IOT after SSID of AP", that is, the terminal only judges whether the SSID of the node includes the SSID of AP and whether includes the suffix "-IOT", as long as the two conditions are satisfied, and the terminal does not need to judge for other fields in the SSID of the node.
In another embodiment, the method further comprises:
and if the RSSI of at least one node in the access node list is greater than the RSSI of the target access node, updating the target access node to the node with the maximum RSSI in the at least one node.
In this embodiment, the method is performed after the terminal has successfully accessed the wireless lan, that is, after the terminal has successfully accessed the AP or a relay of the wireless lan, when the location of the terminal is changed, the terminal may determine the RSSI of each node in the access node list again, and if the RSSI of a certain node C is greater than the RSSI of the current target access node, it may be determined that the signal transmission quality of the terminal and the node C is higher than that of the current target access node, so that the target access node is updated to the node C, and the terminal establishes a connection with the node C.
In addition to updating the target access node when the terminal location changes, the terminal may also perform periodic RSSI determination according to a certain period.
In this embodiment, after the terminal accesses the current target access node, a new target access node may be further determined according to the RSSI, thereby ensuring that the signal transmission quality between the node to which the terminal accesses and the terminal is optimal.
On the basis of the foregoing embodiment, the present embodiment relates to a specific method for a terminal to acquire an SSID of an AP in a wireless local area network, that is, before step S101, the method further includes:
and the terminal acquires the SSID and the password of the AP in the wireless local area network through configuration.
Since the terminal determines the access node according to the SSID of the AP, the terminal needs to acquire the SSID of the AP in the wireless lan before that, so as to ensure that the access node is determined according to the SSID of the AP subsequently. Meanwhile, the terminal also needs to acquire the password of the AP for subsequent use in establishing connection with the access node.
As an alternative, the terminal may obtain the SSID and password of the AP in a specific SmartConfig manner. For example, for an intelligent camera, a user may use an Application (APP) provided by a manufacturer of the intelligent camera to input an SSID and a password of an AP of a wireless lan in the APP, so that the intelligent camera may obtain the SSID and the password of the AP of the wireless lan.
On the basis of the foregoing embodiments, the present embodiment relates to a process in which the terminal establishes a connection with the target access node after determining the target access node, that is, after the foregoing step S104, the method further includes:
and if the target access node is the relay, establishing connection with the relay through the SSID of the relay and the password of the AP.
When the relay accesses the wireless local area network, the relay already acquires the password of the AP of the wireless local area network, wherein the relay can also acquire the password of the AP of the wireless local area network by the configured method. Furthermore, if a terminal needs to access the relay, the relay needs to provide the password of the AP of the wlan to the relay, and the relay determines whether the terminal can access successfully according to the password of the AP provided by the terminal.
Therefore, on the basis of the aforementioned configuration to acquire the password of the AP of the wireless local area network, when the terminal has determined that the target access node is the relay and needs to establish a connection with the relay, the terminal establishes a connection with the relay by the SSID of the relay and the password of the AP of the current wireless local area network.
Fig. 4 is a flowchart illustrating a wlan access method according to an exemplary embodiment, where, as shown in fig. 4, the method is performed in a complete manner:
in step S301, the terminal acquires the SSID and the password of the AP in the wireless lan by configuration.
In step S302, the terminal transmits a wireless local area network access broadcast message.
In step S303, the terminal receives a response message sent by at least one receiving node, where the response message includes an SSID of the at least one receiving node.
In step S304, the terminal adds the AP in the at least one receiving node to the access node list.
In step S305, if the first receiving node is a relay, it is determined whether the SSID of the first receiving node is obtained according to the SSID of the AP by using a predetermined algorithm, and if so, the first receiving node is added to the access node list.
In step S306, the terminal determines the target access node according to the RSSI of the AP and the RSSI of the relay corresponding to the access node list.
In step S307, if the target access node is the relay, a connection is established with the relay by the SSID of the relay and the password of the AP.
The specific execution method of the above steps can refer to the foregoing embodiments, and details are not described here.
